COTTON-SEED CLEANER.

SPECIFICATION forming' part Of Letters Patent No. 399,819, dated March 19, 1889*.

Application filed .Tuly 21. 1888. Serial No. 280,601. (No model.)

To @ZZ whom it may concern.-

Be it knownthat I, CHRISTIAN BAUMGAR- TEN, of Schulenburg, in the county of Fayette and State of Texas, have invented a new and Improved Cotton-Seed Cleaner, of which the following a full, clear, and exact description.

The object of the invention is to provide a new and improved cotton-seed cleaner, which is simple and durable in construction and very effectively removes all impurities from the shell of the seed.

The invention is to be used in connection with a machine for removing short lint from cotton-seed, for which I filed an application in the United States Patent Office, of even date herewith, Serial No. 280,602.

The invention consists of a revolving horizontal disk-brush and of a fixed table provided with emery-slabs and perforated plates in contact with the brush.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the iigures.

Figure l is a sectional side elevation of the imprmiement, and Fig. 2 is a plan view of the fixed table with parts removed.

The improved cotton-seed cleaner is provided with an outer shell or casing, A, in which is secured a fixed table, B, consisting of an open wheel, C, supporting on top emery slabs or plates D and metallic perforated plates E, placed alternately with the said emery-slabs I) and plainly shown in Fig. 2.

The upper surface of the table B is in contact with the ends of the bristles of the brush F, which is formed in the shape of a disk and secured to a vertical shaft, G., mounted to rotate in suitable bearings and passing centrally through the casing A and the table B. The brush F is provided near its hub with openings II, registering with the lower end of a hopper, I, held on top of the casing A. From one side of the latter leads au outlet-pipe,

J, through which passes the cleaned cottonseed.

To the bottom of the casing A is secured a coneshaped receptacle, K, into which open the perforated plates E of the table B. A pipe, Il, leads from the lower end of the inverted cone-shaped receptacle K, and is connected with an exhaust-fan. A jacket, N, is held in the said receptacle K and the table B and incloses the shaft G, as is plainly shown in Fig l.

The operation is as follows: In the application above referred to the short lint is removed from the cotton-seed, but impurities still remain on the seed, and hence the lat` ter, after leaving the said machine, is discharged into the hopper I of the present device,so as to pass into the interior of the casing A, onto the back of the brush F, and through the openings Il onto the top of the table B. The seed now passes between the bristles of the brush F and the top surface of the table Btl1at is, onto the top surface of the emery-slabs D and the perforated plates E. As the seed is whirled through between the brush F and the table B, the last particles of lint and other impurities are removed from the seed, which latter finally passes into the casing A, and from said casing through the downwardly-extending chute J to a suitable receptacle or bag. The impurities removed from the seed pass through the perforations in the perforated plates E and fall into the receptacle K, from which they are removed by the action of the suction-fan connected with the pipe L. The action of the suction-fan also greatly assists in passing the impurities through the perforations in the plates E. The perforations in the plates E may be round, oblong, or other desired shape. Thus it will be seen that the cotton-seed is cleaned very rapidly of all its impurities, which are at the same time separated from the cotton-seed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A cotton-seed cleaning-machine consisting of the horizontal circular fixed table B, having alternating emery-slabs and perforated plates, a casing, A, inclosing the table and IOO provided with hopper I ou its top and-the seed-outlet J on its side, the cone-shaped receptacle K, under the table and having` Ithe tubular Central jacket, N, extending from its 5 bottom upwardly through the Center of the table, the outlet L at the bottom of the receptaole, the shaft G, extending through the oasing and jacket K, and the eireulai' brush on the shaft Within the casing and having openings II, Substantially as set forth.
